I work for a trading company, and today I was eating dinner alone. My wife is a manager and we both work, so we don't get to spend time together because work takes priority. When she comes home every once in a while, she's exhausted from the stress she's been making and demanding. My sister-in-law, Azusa, can't stand to see us like this, and she often comes over to our house. We naturally get into a conversation about our marital lives, and with a devilish smile on her face, Azusa starts playing with my crotch. She then whispers in my ear that if I can hold off on ejaculating for 30 days, I can do whatever I want with her...
